Which equation BEST represents this situation?
Responses
A 45x = 2.545x = 2.5
B 2.5x = 452.5x = 45
C x + 2.5 = 45x + 2.5 = 45
D x + 45 = 2.5

B 2.5x = 45

The correct equation that represents this situation is option B:

2.5x = 45

Explanation: Let x represent the number of collectible dolls Miranda can buy. Since each doll costs $2.50, the total cost of the dolls is equal to the number of dolls multiplied by the price of each doll, which is 2.5x. And she has $45.00 to spend, so the equation becomes 2.5x = 45.

To find out how many dolls Miranda can buy, you need to divide the total amount of money she has ($45.00) by the cost of each doll ($2.50). You can set up an equation to represent this situation.

Let's denote the number of dolls Miranda can buy as "x". Since she can buy x dolls, the total cost of those dolls would be 2.50x.

We can set up the equation as follows:

2.50x = 45.00

Option B (2.5x = 45) correctly represents this situation, where x represents the number of dolls Miranda can buy, and 2.5x is the total cost of those dolls.
